Synthesis of new 1,2,3-triazole derivatives of uracil and thymine with potential inhibitory activity against acidic corrosion of steels

Abstract

Ten 1,4-disubstituted 1,2,3-triazoles were synthesized from one of 1-(azidomethyl) benzene, 1-(azidomethyl)-4-fluorobenzene, 1-(azidomethyl)-4- chlorobenzene, 1- (azidomethyl)-4-bromobenzene or 1-(azidomethyl)-4-iodobenzene, generated in situ from sodium azide and the corresponding benzyl halide, and dipropargyl uracil or dipropargyl thymine. Optimal experimental conditions were established for the conventional click chemistry. The corrosion inhibiting properties of some of these compounds, which were determined by means of an electrochemical technique, are also presented. © 2013 by the authors.
